WARNING: Risk of electric shock. Risk of fire. Install IQ Sealing Caps on all unused AC connectors, as
these connectors become live when the system is energized. IQ Sealing Caps are required for protection
against moisture ingress.
NOTE: If you need to remove an IQ Sealing Cap, you must use the IQ Disconnect Tool. See “
Disconnect a
Microinverter” on page 27.
Step 7: Terminate the unused end of the cable
Terminate the unused end of the IQ Cable as follows.
A. Remove 13 mm (½ in) of the cable sheath from the conductors. Use the IQ
Terminator loop to measure 13 mm.
B. Slide the hex nut onto the cable.
C. Insert the cable into the IQ Terminator body so that each of the two wires
lands on opposite sides of the internal separator. The grommet inside the
IQ Terminator body must remain in place.
D.
Insert a screwdriver into the slot on the top of the IQ Terminator to hold it in place.
E. Hold the IQ Terminator body stationary with the screwdriver and turn only the hex nut to prevent the
conductors from twisting out of the separator. Torque the nut to 7 N m.
F. Secure the terminated cable end to the PV racking with a cable clip or tie wrap so that the cable and IQ
Terminator are not in contact with the roof surface.
NOTE: Turn only the hex nut to prevent conductors from twisting out of the separator.
WARNING: The IQ Terminator cannot be re-used. If you unscrew the nut, you must discard the IQ
Terminator.
